PATENTFFICE n NEW YORK, N. Y., A CORPORATION OF ILLINOIS LUBRICATING SYSTEM FOR INTERNAL' COMBUSTION ENGINES Application led July 23,

This invention relates to certain new and useful improvements in lubricating systems for internal combustion engines and more particularly to the construction of drip spoon carried by the diaphragm whereby the oil drawn through the diaphragm by the sucv tion of the engine will drop one drop at a time in order to allow the drops to be counted in order to record the amount of lubri-k cant being fed to the cylinders of the engine.

The natureof this invention is a slight improvement over the drip spout disclosed in an application filed by Vernon W. rIhompson and Burt N. Pierce, December 8, 1930, Serial Number 500,928.

A still further object of the invention is to provide a drip spoon which is provided with a trough portion and a tongue, the trough portion being adapted tobe secured to the diaphragm by an apertured plug through which the lubricant passes into the trough portion and then from the trough portion onto the tongue portion in order to allow it to drop a drop at a time in front of the sight opening.

@ther and further objects of the invention v will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawing,

Figure l yis a vertical section showing the diaphragm drip spoon in position;

Figure 2 is a vertical section taken atY right angles to that of Figure l showing the diaphragm and drip spoon vin section with the cooperating needle valve working in the plug for holding the drip spoon in position on the diaphragm; and

Figure 3 is a detail perspective view of the drip spoon and a portion of the diaphragm and the apertured plug and nut for holding the same.

As shown in the application iiledby Vernon lV. rllhompson and myself, Serial Number 500,928, a housing A is employed in connection with my improved construction of lubricating system having an inlet l and an outlet 2, said housing being provided with a flexible diaphragm 3 and a sight opening et. The'lubricant to be supplied to the engine is 1931.` serial No. 552,726.v

adapted to be drawn from a source of supply through inlet l through the 'diaphragml and out through the outlet 2 so as tov lubricate the valves and walls ofthe cylinders.y

in a companion application filed even date l herewith, I have shown and described the particuiar,construction of housing land thel invention in this application resides in the particular' construction 'of dripspoon.

r'he iiexible dia hraO'm 3 forms two cham- Ybers'in the housing, one of which isin com-f` munication with the inlet l and the other with the loutlet 2. y

The =diaphragm is provided with a central opening through which is adapted to pass an'apertured threaded plug 5 for securing the drip Vspoon in position on oneA 7 which clamps the head of the threadedy plug 5 against the bottom of the trough .of thel drip spoon as clearly shown. e l

llhe drip'spoon is provided with an. inclined wally 8 which terminates in a substan tia-ily downwardly and outwardly projecting Vshaped tongue 9 from which the lubricant passinoi through the apertured plug is adapted to drop a drop at a time in front'of the sight openingll.

l/Vith this construction the drip spoon can be readily secured in position on the diaphragm and removed therefrom and by employing an apertured plug, l form a valve seat for a needle valve l0 which regulates the passage of the lubricant passing from a source of supply to the engine.

From the foregoing description it will be seen that I have provided a lubricating system for an internal combustion engine cooperating with a needle valve for regulating the supply of lubricant to the engine, said diaphragm carrying a drip spoon locked in its adjusted position by a plug and nut.

What I claim is Vl. In a lubricating system for an internal combustion engine having a housing, a flexicc ible apertured diaphragm mountedin said f housing throu h which lubricant is adapted to pass :from t e source of supply to the engine and a drip spoon disposed under the aperture of said diaphragm, f
